RCBS Full Length Die Set - Group D - Bottleneck Rifle Cartridge 5.7X28

The RCBS Full Length Die Set for 5.7x28 bottleneck rifle cartridge is a precision reloading system designed for shooters who demand repeatable, SAAMI-spec ammunition. This Group D die set includes a full-length sizer die with integrated expander-decapping unit and a seater die with bullet seater plug—the core components needed for consistent case preparation and bullet seating on one of the most controllable modern rifle cartridges.

The full-length sizer die brings cases to SAAMI minimum cartridge dimensions, sizing the case exterior, removing spent primers, and expanding the neck to proper diameter for bullet seating. Engineered vent ports prevent trapped-air damage and excessive lubricant buildup—critical for maintaining case integrity across multiple reloading cycles. Headspace is held to minimum tolerances, ensuring that fired cases are restored to specification and deliver the consistency that bottleneck cartridges demand for reliable feeding and accuracy.

Reloaders working with 5.7x28 ammunition benefit from this die set's precision engineering, whether preparing ammunition for precision rifle training, defensive carbine qualification, or high-volume range work. The 5.7x28 platform has gained adoption across military, law enforcement, and civilian precision communities, and proper case preparation is essential to maintaining performance and extending brass life. RCBS die sets are engineered to tight tolerances and backed by decades of reloading tool manufacturing experience.
